+CUE Structs are JSON objects but with a cleaner syntax. Lists and Function
+arguments behave like JSON's.
+See |splitjoin-json|.
+
+Structs ~
+
+Structs are first class, so the cursor can precede the first curly brace.

+Function Arguments ~

+Function splitting requires the cursor to be positioned inside the
+parenthesis, preferably near the closing one.
